Enhanced LoRa-Based Underground Communication Using Repeaters for Range Extension

The project “Enhanced LoRa Based Underground Communication for Mining Using Repeaters” focuses on improving communication in underground mining environments. Underground areas usually face signal loss and communication difficulties due to obstacles and long tunnels. In this system, the ESP32 microcontroller collects data from sensors such as the DHT11 sensor and vibration sensor. The data is displayed on the OLED display and alerts are generated using a buzzer during abnormal conditions. The LoRa RA-02 module with a whip antenna is used for long-range wireless communication. Repeaters are used to extend the communication range inside tunnels. This system provides reliable monitoring and improves safety for miners in underground environmentsora humidity and temperature outpu
